' TRACK CONSTRUCTION.

Specification of Letters Patent. Patented Jan, 18, 1910,

Application filed October 16, 1907. Serial No. 397,624.

tudinal axis of the tie.

The distinguishing features of the present invention comprise a tie with shoes in which a supporting block can be fitted to support tracks and with which suspended joints for said tracks can be used.

The invention is specially applicable to concrete track construction.-

In the drawings, Figure 1 represents a side elevation of one form of the tie embedded in concrete, Fig. 2 shows a top plan view of Fig. 1, Fig. 3 is a left hand end view of the tie shown in Fig. 1, Fig. 4 represents a. partial section of Fig. 2 on the line 4, 4, Fig. 5 represents a plan view of a tie with m v invention modified to support a joint of the track on a double end, Fig. 6 shows a partial section of Fig. 5 on the line 6, 6, Fig. 7 is a partial section of Fig. 5 on the line 7, 7, Fig. 8 shows a modification of Fig. 5, and Fig. 9 represents a section of Fig. 8 on the line 9, 9. 7

Referring to Figs. 1 to 4, a tie is represented with the bottom flange 20, from which extend a pair of shoes, each of which latter is formed with the inclined side walls 22 and the straight wall 23. The walls 23 are located on the opposite sides of the longi- The walls 22 approach each other as they extend from the flange 20, and the an 23 is perpendicular to said 'flange. The shoes are connected by the central rib 25 and have extending from their outerinclined walls the ribs 26. The rib 25 has formed therein the openings 28. In each of the shoes is located a bearing block 30 which latter is forced into the shoes so as to tightly fit therein, and project a little above the upper edges thereof. Spikes 31 may be driven through openings in the sides 22 of the shoes into said bearin blocks -to hold them in place. A plate 32 is fitted into the top of each block 30 and which? supports the rails-33, by means of screws 34: or spikes. The tie is embedded in a bed of concrete Referring to Figs. 5, 6 and 7, a tie is shown with a single member at one end and a pair of members 51 at the other end. From the said member 50 ex tends a shoe with walls 52, 53 similar to 22,

23, and from each of the members 51 ex tend shoes with walls 54, 55, also similar to 22, 23.. The. walls are preferably locatedto face each other as shown. Between the walls 55 and joining the members 51'is formed a pocket 60. In the shoes of this modified tie are located supportingblocks 65, 66, similar to the blocks 30. In the pocket 60 is located a third supporting block 67. A rail is carried on the supporting block 65, and rails 71, 72 are supported on the blocks 66, the abutting ends of the latter rails meeting on the central block' 67. The inner wall 52-is connected with the inner walls 64 bythe rib 73 having open- I lngs 74,.and a Mb 75 extends from the outer wall 52, while ribs 76 extend from the outer walls 54. I

In the modification shown in Figs; 8 and i 9 a tie is represented with a single member 80, having a shoe with walls 81, 82, similar to 22, 23 and a supporting block 83 similar to 30. The latter tie at.its other end has formed therewith a pair of membersi86 connected at their outer ends and provided with shoes-having the walls 87, 88 similar to 22, 23 and blocks 89 similar to the blocks 30. The members 86 are connected "by an end connection 90. A central rib" 9]..con-

nects the shoes, and a rib 92 extends from the outer wall 81, while ribs 93 extend from the outer walls 87. Between the walls 88 is formed a pocket 95, over which extend the ends of the rails 96, 97 that are carried on the blocks 89. The latter disposition of parts allows the introduction of the sus ended joint for the rails as shown, or a loo may also, be located in the pocket 95 to bear up against the ra-ils.

are placed practically-parallel to each other,-

"and support rails on their supporting blocks,

avoiding the use of longitudinal stringers to support said rails.

Although concrete is shown with the tie in Fig. 1, ballast may be substituted therefor, and either concrete or ballast may be used for any of the forms of ties represented. The openi s in the ribs like 28, allow the concrete or allast to bind the tie in place.

Having described my invention I claim:

1. In a metal tiefor track construction, the combination of an upright wall extending lengthwise of the tie and two upwardly converging transverse walls forming a shoe, a wood bearing block secured in the shoe and projecting above its walls, and a plate embedded in the ceive therail.

2. A tie for track construction comprising a casting having a single integral shoe at one end and a pair of separate alined integral shoes at' the other end, and rail supporting blocks in said shoes.

3. A tie ing a casting having a single member at one end and a'pair of members at the other end, a bottom 'fiange connecting said members, and a branched rib on said flange connecting said singlemember with each of the other members. a

4. A tie for track'construction comprising a casting havinga single integral shoe at one end and a pair of integral shoes at the other end, a branched'rib connecting "the single shoe with each of the ;'other shoes, and rail supporting blocks in said shoes.

5. A tie for 'tra'ck'construction comprising a casting havinga single integral shoe at oneendand a pair of"separate' aliried' integral shoes "at the "therend. rail 'sut top-of said block to re for track construction compris-- portingblocks in said shoes, and an integral connection between the single shoe and each of the other shoes.

6. A tie for trackconstruction consisting of a single casting comprising asingle member at one end and a pair of members at the 5 other end, a bottom flange beneath said members, and a connection between the flanges beneath said pair of members.

7. In a tie for track construction the combination of a single member at one end of 5 the tie, a pair of members at the other end thereof, a shoe formed with each member, a supporting block located in each shoe, and a pocket connecting the shoes of the double member.

8. In a tie for track construction the combination of a single member at one end of the tie, a pair of members at the other end thereof,- a shoe formed with each member,

block located ineach shoe, a 6() pocket connectin the shoes of the double member, and a hick located in said pocket, a rail on the block of the single member,

a supporting and rails on the blocks of the double memher, the block; in the pocket supporting abutting ends of the latter rails.

9. In a tie the combination of a flange, a shoe at each end of the flange, supporting blocks in the shoes, and a wedge bearing between each block and flange to hold the block in. place in its shoe.
